Title: Encoding and decoding method and its device
Inventor: NOMIZU YASUYUKI
IPC: H04N19/93
Filed: 1994-03-18
Abstract: PURPOSE:To effciently execute entropy encoding and to improve the encoding compression rate of natural picture data by executing exclusive OR processing between a noticed picture element and its adjacent picture element on the prestage of entropy encoding. CONSTITUTION:Picture data PA from a picture input part 1 are applied to a bit plane developing part 2 and decomposed to a bit plane, which is stored in a picture memory 3. An exclusive OR operation part 4 forms exclusive OR between the picture data of each picture element position in the picture data of each bit plane stored in the memory 3 and that of an adjacent picture element adjacent to the preceding position of the picture element position concerned in a main scanning direction while using the contents of a work memory 5. The processed result is applied to a run length encoding processing part 6 as picture data PB. The processing part 6 applies prescribed run length encoding processing to the data PB to execute compression encoding and outputs encoded data CDa. Since entropy is reduced prior to encoding, the efficiency of encoding can be improved.
Patent JP-H04308469-A (JP)
Title: Power supply
Inventor: FUKUSHIMA YOSHIO
IPC: H02M7/12
Filed: 1991-04-05
Abstract: PURPOSE:To suppress fluctuation of output voltage without requiring a transformer by decreasing power supply to a capacitor and a load upon output voltage rise whereas increasing power supply upon output voltage drop. CONSTITUTION:When load current decreases and the output voltage across a capacitor 5 reaches the operating voltage of a constant voltage diode 8a, a transistor (Tr) 10b is turned ON and a voltage appears across a resistor 10a. When that voltage reaches the ON voltage of a Tr 11b, the Tr 11b is turned ON. At the same time, a Tr 10c is turned ON and the output voltage across the capacitor 5 drops. Consequently, the current flowing into a load 13 increases and when the output voltage drops to the operating voltage of a constant voltage diode 9a, a Tr 9b is turned OFF and a Tr 9e is turned ON. Collector-emitter voltage of the Tr 9e goes substantially to 0 and the Tr 10b is turned OFF. Consequently, a first switch circuit 4 is operated through a first voltage reference generating circuit 6.

Filed: 1984-04-11
Abstract: PURPOSE:To obtain a fine porous clay material having desired pore diameter, by mixing a smectitie mineral with a water-soluble polymer, cation, alkali and water, cooling the mixture, and removing the water-soluble polymer therefrom. CONSTITUTION:A smectite mineral such as montmorillonite is mixed with an aqueous solution of a water-soluble polymer, and the mixture is mixed with a cation selected from the group IV or group VIII elements, etc. of the periodic table. In this state I , the interlaminar distance is increased by the development of the structural viscosity of the water-soluble polymer irrespective of the presence of the cation between the layers of the mineral. An alkali such as NaOH is added to the mineral of the state I to form a jelly precipitate. The product is heated and dried to remove the water between the layers to attain the state IIin which the extension of the chain of the water-soluble polymer is decreased. The mineral of the state II is heated at about 300-700 deg.C to calcine and remove the water-soluble polymer existing between the layers to obtain the state IIIwherein the columns of an inorganic material are left between the layers. A porous clay material having a pore size of about >=20Angstrom  can be prepared by this process.

Title: Ice water transporting device
Inventor: FUJITA TAKASHI
IPC: F25D17/02
Filed: 1993-03-31
Abstract: PURPOSE:To improve a concentration-adjusting capability for increasing a concentration of ice by a method wherein a concentration adjusting means is composed of a double pipe comprises of an inner pipe arranged horizontally and an outer pipe formed with a water discharging port, and the inner pipe is a porous pipe in which a plurality of holes for passing only water are formed at a lower side thereof. CONSTITUTION:A concentration adjusting means 6a is constructed such that a flowing-in pipe 62 and an inner pipe 66 and the like are arranged horizontally, and an ice water flowing direction from the flowing-in pipe 62 becomes horizontal, so that ice in the ice water flowing in the inner pipe 66 is flowed by its buoyancy toward an upper part of a pipe, and a flow with small amount of ice flows at a lower part thereof. Since the inner pipe 66 is provided with holes from the center of the pipe to the lower part for discharging ices, the less is a disturbance of flow of ice water, the less a possibility of the ices passing near the holes is. Accordingly, a large amount of water is discharged, and a concentration adjustment for sufficiently increasing a concentration of ice can be carried out.

Title: Turbine rotary blades connector
Inventor: KUNO KATSUKUNI
IPC: F01D5/22
Filed: 1980-06-04
Abstract: PURPOSE: To restrain untwist and damp vibration of rotary blades by bringing upward a pair of connecting members engaged with each other, into contact with vizors in fore and back edges of adjacent rotary blades during an operation, so that said rotary blades may be engaged with each other.  
     CONSTITUTION: Connecting faces 18, 19, which are faces of end parts 12a, 13a of connecting pieces 12, 13, come in contact with each other during an operation and forces act to each other for restraining the amount of untwist of rotary blades within a desirable limit. In case rotary blades 1, 2 vibrate in X direction, that is, the circumferential direction, a very small sliding motion is started between connecting faces 18 and 19 of connecting pieces 12 and 13, and principally the friction between said faces 18 and 19 exhibits a significant effect on damping the vibration. While in case the rotary blades vibrate in Y direction, that is, the axial direction, principally the frictional force on faces of the connecting pieces 12, 13 touching the lower faces of vizors 8a, 9b of rotary blades 1, 2 which is a pressure receiving surface of centrifugal force of connecting pieces 12, 13, are quite effective on damping vibrations.
